A Computer with Lights, Get Inside, See What’s Happening

It’s 10 meters long and 2 meters high. It’s made of discrete transistors and LEDs. You can actually see what’s going on. Is it a real working computer? Yes. Can you program it? Yes. Why was it made? The developer, James Newman, says, “Computers are quite opaque, looking at them it’s impossible to see how they work. What I would like to do is get inside and see what’s going on. Trouble is we can’t shrink down small enough to walk inside a silicon chip. But we can go the other way; we can build the thing big enough that we can walk inside it. Not only that we can also put LEDs on everything so we can actually SEE the data moving and the logic happening.” Behold, the Megaprocessor
